From Excel to Python: A Realistic 90-Day Transition Plan

The short version

The uncomfortable truth about from excel to python is that most organisations treat it as a tooling problem when it is, almost always, a decision-making problem.

Start with the constraint rather than the ambition. In most Indian organisations the binding constraint is not talent or budget — it is the absence of a clear owner. Once a named person carries the outcome, the sequencing question tends to answer itself.

Where teams get it wrong

Finally, there is the question of who pays and who benefits. When those are different groups, adoption stalls regardless of how good the design is. Aligning them is unglamorous work and it is usually the work that matters.

Scale changes the answer. What works for a fifty-person team fails at five hundred, not because the idea was wrong but because the coordination cost grew faster than the benefit.
